1,4-Dichloro-2-nitrobenzene is an organic compound with the formula C₆H₃Cl₂NO₂. One of several isomers of dichloronitrobenzene, it is a colorless solid that is insoluble in water. It is produced by nitration of 1,4-dichlorobenzene. It is a precursor to many derivatives of commercial interest. Hydrogenation gives 1,4-dichloroaniline. Nucleophiles displace the chloride adjacent to the nitro group: ammonia gives the aniline derivative, aqueous base gives the phenol derivative, and methoxide gives the anisole derivative. These compounds are respectively 4-chloro-2-nitroaniline, 4-chloro-2-nitrophenol, and 4-chloro-2-nitroanisole.^[1] Isomeric with this compound is 1,2-dichloro-4-nitrobenzene.
